统一轨距事件
2076年，萨特国铁将实行国际统一轨距1435mm，普客车辆标准长度25.5m，动车组标准编组16编，在全国范围内启用GSM-R+ATP系统调度
这将导致北方三省、中部二省的内部轨交无法和萨特国铁联通（北方三省地上轨交轨距1115mm，中部二省地上轨交规矩1305mm）
同年，萨特北方铁路集团正式建立，该公司收购了西格尔基省铁、霍利铁路集团和西霍省铁管局集团。此后，萨特国铁宣布，使用电子路票全面取代实体路票。此前萨特60km/h的慢速列车使用实体路票。
各方动作
萨特最高检湾区省派出署起诉湾区省政府到萨特最高法，萨特最高检湾区省派出署援引湾区省使用的西部联合省宪法第十条，联合省对于私人财富及私营事业，认为有妨害国计民生之平衡发展者，应以法律限制之。萨特最高检认为，湾区省对全国的列车倾销妨害国计民生和平衡发展，导致湾区独强而其他地方过弱。在最高法移交案件后，湾区省中级法院判湾区省政府对全国的列车倾销违法，罚款22万中央元。
湾区省中级检察院援引西格尔基法律总汇第二十六条社会民主党是西格尔基省执政党，其他党派是参政党，起诉西霍省和西格尔基省，要求CPS从此二省下台。
西霍省法院遵照银诉雷系案，认定萨特国铁作为非西霍省企业，无权冲击西霍省自由市场。西霍省动用一切力量捍卫西霍省的自由市场，因此对萨特国铁发动制裁。
卡达托姆省认为，湾区省对CPS的指控毫无理由。柯西比省随后发动代号八一的军演。
The Standard Gauge Unification Event
In 2076, the Sutter National Railway will adopt the international standard gauge of 1435mm. Standard passenger cars will have a length of 25.5 meters, and standard train sets will consist of 16 cars. The GSM-R+ATP system will be implemented nationwide for scheduling.
This will result in the internal rail transit systems of the Northern Three Provinces and the Central Two Provinces being incompatible with the Sutter National Railway (the Northern Three Provinces use a gauge of 1115mm, and the Central Two Provinces use a gauge of 1305mm).
In the same year, the Sutter Northern Railway Group was officially established, acquiring the Sigelki Province Railway, Holly Railway Group, and Westho Province Railway Bureau Group. Subsequently, the Sutter National Railway announced the full replacement of physical tickets with electronic tickets. Previously, slow trains traveling at 60km/h in Sutter used physical tickets.
Actions Taken by All Parties
The highest prosecutor's office of the Bay Area Province of Sutter sues the Bay Area Provincial Government in the Sutter Supreme Court. The Bay Area Prosecutor's Office cited Article 10 of the Western Union Provincial Constitution, which states that the Provincial Union should legally restrict those who interfere with the balance of national economy and people's livelihoods regarding private wealth and private enterprises. The highest prosecutor's office believes that the Bay Area Province's dumping of trains across the country disrupts national economy and balanced development, leading to the Bay Area being overly dominant while other regions are weakened. After the case was transferred to the Supreme Court, the Bay Area Provincial Intermediate Court ruled that the Bay Area Provincial Government's dumping of trains across the country was illegal and fined them 220,000 Central Yuan.
The Bay Area Provincial Intermediate Prosecutor's Office invoked Article 26 of the Sigelki Legal Compendium, stating that the Social Democratic Party is the ruling party of the Sigelki Province, while other parties are participating parties. They sued the Westho Province and the Sigelki Province, demanding that the Social Democratic Party be ousted from power in these two provinces.
The Westho Province Court, following the Silver vs. Lei case, determined that the Sutter National Railway, as a non-Westho Province entity, has no right to interfere with the free market of Westho Province. Westho Province used all available means to defend its free market and imposed sanctions on the Sutter National Railway.
The Katatom Province believes that the accusations against the Social Democratic Party by the Bay Area Province are unfounded. Subsequently, the Kosibi Province launched military exercises under the codename "81".
